How to grow it
It wants full sun, water it very low, and give it lean, well-drained soil. Target a soil pH around 6.5–8.0. Space plants about 18 in apart. Expect roughly Blooms spring–summer. Hardy native perennial.
How it's used
Winecup is used: ornamental; pollinator.
🔎 How to identify it
- Deeply cut palmate leaves
- Trailing stems
- Cup-shaped wine-magenta flowers

How to grow & propagate winecup
Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.
How to propagate winecup
The mallow family loves heat. Sow the seed once the soil is thoroughly warm — soaking it overnight helps the hard coat — and give it full sun. The perennial members (Turk's cap, rock rose) also root from softwood cuttings taken in early summer.
Growing winecup in Texas
Give it full sun and lean, well-drained soil. Match the spot to the plant and most of the battle is already won.
Time your planting to our long warm season and watch the frost dates at both ends; the live weather tool on this site is built for exactly that.
Once it's rooted in, this is a low-water plant — overwatering does more harm than drought here. Water deeply to establish, then back off and let it prove how tough it is.
Harvesting
Figure on roughly blooms spring–summer before you're harvesting.
Making more for free
If you want more, let your healthiest plants mature fully and collect the seed once it's dry on the plant — then store it somewhere cool, dark, and dry until next season.
