Welcome to DVIS!



(Please contact the owner before visiting a PRIVATE HOME garden)


Thanks to all those who have opened their gardens to our members. This year there are 12 gardens in the DVIS Open Garden Program.  Our hosts invite you to visit their gardens. They are very proud of their gardens and want you to see the product of all their hard work.  They would be very disappointed if you didn't visit.

Some gardens are large and some are smaller, but all have a lot to offer the visitor. It is a wonderful opportunity to see different and newer varieties of irises, to witness how they are grown, and to get acquainted with other iris enthusiasts.  This year, eight of the gardens are also enrolled in the First- Year Introduction Program. This is a chance to see some of the very newest varieties by notable hybridizers. And it is an excellent opportunity to make out your wish list for those that will be distributed later this year. 

All the open gardens are listed below. Please call or email the host before you visit. The host can help you with directions. And, for your convenience, the irises will have name tags.

Jen Cunningham, open garden chair, has put together self-guided tours for the open gardens. For a copy, contact Jen: or (610) 767-2712. If you are interested in adding your garden to the open garden list for next year, fill out the attached form and mail it back to Jen.  Please resolve to be a visitor in this the year of our golden anniversary.

Garden Etiquette

With bloom season fast approaching, I thought it appropriate to have some reminders on how to act while in someone's garden.

Private gardens are best seen by appointment. It is best to call ahead. Please phone in advance for directions and to set a mutually acceptable time for viewing the garden. Arrive promptly for your garden tour. Remember that Mother Nature does not always agree with our plans - or our anticipated bloom times! Remember that you are there to see the garden, so you may not be given a "house tour". While your host may offer you food and drink, you shouldn't expect it.

Wear sensible shoes, and expect to get them dirty. A hat or sunscreen should be brought along to protect you from the sun's rays. You are bound to see something you like, so bring a notepad and pen for future reference.

Please do not touch or pick the flowers! Some gardeners are iris hybridizers. They need the blooms for this purpose and you could upset their hybridizing efforts by touching tags or picking flowers that they need to make crosses. They may have already made a cross and are waiting for the seed pod to ripen. This is why it is very important not to "help" by doing any deadheading in the garden.

Don't move any plant markers. If you question the accuracy of one, share your concern with your host, rather than trying to guess where it should go.

Be careful with your umbrella, handbag, and camera. Also take care not to disturb any tags while walking through the garden. Most gardeners have a tendency to plant too close, so watch your feet! And always stay on the provided walking paths. The most common cause of broken stalks seems to be people trying to climb over a row as a shortcut.

P-l-e-a-s-e - NO uncontrollable pets or children! Many gardens have rare or valuable plants that could be damaged.

Do not ask for (or take!) plants or seeds.

Lastly, and most importantly... Please remember that you are a guest. These gardeners are extending themselves and their gardens for your benefit. They do this freely on a volunteer basis. Have Fun! Ask questions! But please...leave the garden as you found it! (Unless you want to do a bit of weeding... ;=)
