2023 SymROSEium A Season of Roses: Rose Care Throughout the Seasons

April 8 @ 9:30 am - 12:30 pm

Please join us for our annual SymROSEium. This year’s theme is –

A Season of Roses: Rose Care Throughout the Seasons

April 8, 2023 – 9:30AM to 12:30PM
Mitchell Hall, Denver Botanic Gardens

Spring is just around the corner and a wonderful way to start the Spring rose growing season is to attend the annual SymROSEium at the Denver Botanic Gardens. This year three speakers will present what we should do each season in the rose garden. Topics will include pruning and planting roses in the Spring, watering and fertilizing during the Summer, and deadheading and winterizing in the Fall.

A question-and-answer period will follow the presentations. Consulting Rosarians will be available during the break and after the question-and-answer period.

A new edition of ‘Growing Roses in Colorado’, will be available for sale.

We will also have the Plant Select HALF PINT® pineleaf penstemon available for sale. “HALF PINT® pineleaf penstemon has scarlet-red, trumpet flowers that call hummingbirds and butterflies from June to August. A profusion of flowers blooms right above a tidy mound of soft, needle-like foliage.”  Read more about this plant HERE.

We’ll also be introducing a new fertilizer, Darn Good Fertilizer. A small amount of the fertilizer will be available for sale at the SymROSEium and we will also be taking pre-orders. We will have a large selection of High Country Roses for sale. Please be sure to join us, we’d love to see you!

Admission is always free with paid entrance to Denver Botanic Garden if you’re not a DRS member or garden member.

Getting into Denver Botanic Gardens has changed from a few years ago. Anyone who is a DBG member or visitor needs a timed ticket to enter the gardens and into Mitchell Hall for the free SymROSEium. Click HERE for a ticket.

Denver Rose Society members just need to show their membership card at the gate. Cards are available under Members on the Denver Rose Society website.

Don’t miss the fun!

Checks and credit cards will be accepted for sale items.

No pre-registration is required.
