Flower of the Week – Camassia Quamash

Camassia Quamash, otherwise known as the Common Camas, is a prominent flower in our beautiful Centennial garden. You will notice this flower quickly, with its lavender/blue petals. Right now is the perfect time to come see these amazing plants, as they typically are in full bloom around the end of April into early May. When planting the Common Camas at home, make sure you do not place it too deep into the soil. Like many of the other flowers seen around the Chautauqua campus, the Common Camas should be planted in the fall







Blooming Now

Mahonia Repens – Colorado Creeping Holly blooms in April and May in most years. It is native to Colorado. A broadleaf evergreen stoloniferous plant that can populate an area through underground stolons as well as from the fruit, it is beautiful in all seasons and pollinator friendly. The yellow flowers produce a grape colored berry which birds and small mammals relish after it matures in the fall.  It has holly-like foliage that will turn red and/or purple in the fall and remain throughout much of winter. It also provides excellent groundcover. Find Mahonia Repens in multiple locations throughout our Chautauqua Campus.




The Allium Oreophilum is one of the most recognizable (and beautiful) flowers on the Chautauqua campus. Known as the Pink Lily, you will recognize it by its (you guessed it!) pink petals. Make sure to stop by the Centennial Garden where these beauties are most prevalent. Similar to other flowers in our gardens, the Pink Lily is at its peak during the end of April and beginning of May.




The Iris Reticulata, otherwise known as the Dwarf Violet Iris, are small, blue plants seen throughout the main campus of Chautauqua. They are at their peak bloom between February, March and April. Be careful when looking for these beauties! They typically don’t grow larger than six inches. If planting these at home, make sure not to plant too deep, as they are smaller plants. The best time to plant is in the fall.





The Acer Saccharinum is one of the most beloved trees in the United States. Blooming at its peak during the months of February, March and April, it is easily recognizable on the Chautauqua campus by its reddish flowers. Its other name, The Silver Maple, is derived from the silvery underside of the foliage. This tree produces winged seeds called Samara’s, which should be planted from May to September. When planting, make sure to plant two (2) inches above ground. This tree will need consistent moisture while growing.

Helpful Hints on Water Conservation: Plant and Lawn Care in the Heat

  1. Prior to watering, probe your soil with a weed digger or an old screwdriver.  If you can penetrate the soil easily, you may not need to water.
  2. If you are checking an individual plant for moisture, probe into the soil one-half inch to one- and one-half inch with your fingers and gather some soil in your hand and squeeze it. If it crumbles, you may need to water. If it forms a nice ball with no water squeezing out of the ball the plant is probably okay for a little while longer. Be careful not to over-water. (Many plants languish and die or become susceptible to disease and insects due to over-watering).
  3. Try and water in the morning. Watering at night can encourage disease and insects. The morning watering is less prone to evaporation and allows the plants to dry before nightfall.
  4. If a plant or lawn is under heat/drought stress, provide some moisture immediately no matter the time of day. Waiting could result in the death of the plant or the continued stress could make it more susceptible to disease and or insects.
  5. Most soils can only absorb a small amount of water at a time. Especially if they are dry prior to watering. Try cycling your irrigation by providing no more than a couple of tenths of an inch per cycle. This means probably no more than 10 to 15 minutes maximum per zone per cycle. Invest in an inexpensive rain gauge or two or three to help you determine how much water each zone or watering apparatus is providing per cycle then adjust accordingly. (Repurposed old tuna cans would do nicely as well).
  6. Leave your rain gauges out and check them frequently. Sometimes a rainstorm will move through and provide you with a few tenths and then it will clear off. You might arrive home thinking you need to water – and you might – however, you may be able to reduce or even skip a watering based upon what Mother Nature has already gifted you. Adjust your watering accordingly. The water savings can be substantial.
  7. Keep track of rainfall and your watering. Too much water can cause plants and or lawns to succumb to a multitude of other problems. (Many plants and lawns languish or become prone to disease and insects and sometimes die because of over-watering).
  8. Pay close attention to the weather forecast to help gauge what your plants and lawns will require. You might be able to hold off or reduce the amount of watering if the forecast believes the chance of moisture and/or cooler conditions is quite high.
  9. If the forecast calls for cloudy conditions with very little moisture, this is an excellent time to water because you lose very little moisture to evaporation.
  10. If you are fortunate enough to have an automatic irrigation system, be sure to visit and make timing alterations based on rainfall, temperature and the ten-day forecast. Do not set it and leave it that way all season long. Following a rain or in cooler conditions, you might even be able to just turn it off for a day or two (or three or more.) This can result in enormous water savings over the course of a season.

A Water Conserving Plant Favorite Just Beginning to Bloom:

A just-beginning-to-bloom favorite that thrives in very drought (heat) climate, and also does well with a little bit of irrigation, is Amorpha Nan – Dwarf False Indigo. Leaves consist of tiny oval leaflets on erect stems that bend slightly as the as the narrow purplish spikes of flowers bloom in June to July. Situate the Dwarf False Indigo in full sun.

How do you deal with the challenges posed by wildlife at Chautauqua?

Wildlife does pose a challenge for us here on our Chautauqua campus as it does for most gardeners. Rabbits and deer are our main issue. For the most part we try to leave them alone and be tolerant of some of the browsing. We try and improve our odds by selecting plants that have shown to be a little less appealing. That being said, when deer, rabbits or voles are hungry they will take an interest in almost any plant. We have had some success with intermingling a few plants they find desirable with a few undesirables (think Tulips intermingled with Daffodils). Very occasionally we will install temporary fencing or netting. It can also be quite effective to simply shoo them on their way. They will likely make their way back, but we believe it might make them just a little uncomfortable and they could choose to dine elsewhere.

What are your top tips for home gardeners?

Develop a relationship with a supplier or local garden center you trust and be prepared to try something new at their suggestion.  I have learned so much about gardening from taking recommendations from others or trying an alternative when my first choice wasn’t available.

A good example is Platinum Sage – Salvia Daghestanica. I had been planning to order another variety of sage but it was not available, and our nursery person suggested Platinum Sage. It was a good recommendation as it exhibits nice foliage, purple to blue flowers and is quite xeric. (Drought tolerant.)
