How Much Sun And Water Does An Evening Primrose Require?

Filed Under: Perennial Plants, Wildflowers · Keywords: · 1169 Views
I bought a beautiful yellow Evening Primrose today and was wondering how much sun does it need ideally. The tag said sun to shade, but it seems like other things I saw say it needs a lot of sun. Also wondering about water needs to establish and once established? And, finally,does it require deadheading? Thank you.

Answer #1 · Maple Tree's Answer · Hi Melinda-There are several species of the Evening Primrose but most like plenty of sunlight and have low water needs once established. I live in a warm climate and this plant does well in all day direct sunlight. I have grown it in morning shade with afternoon sunlight and even in areas of bright filtered sunlight. It will bloom much better with at least 6 hours of direct sunlight. It is drought and heat resistant and will only need watering a couple of times a week during the summer months. When newly planted I would keep the soil moist, never wet, for for the first month then you can allow the top couple of inches of soil to dry out between waterings. It doesn't require much water and isn't picky about the type of soil but it does need a well draining soil. Too wet a soil is harmful. You don't have to deadhead this plant but it can reseed itself easily. Because of this many consider it somewhat invasive in their garden. Personally I deadheaded the few I have grown before they developed seed pods.

Please ask if you have any other questions.

I bought 2 varieties of these, quite different from each other, one is doing beautifully, but the yellow one has a couple of branches laying down to the ground, not dead but obviously not happy and a couple of branches upright and happy. What should I do, should I cut back the one laying down, how far?

Are the leaves on the branches that are laying down wilting? It sounds like part of the plant may not be getting enough water or possibly the stems are broken or damaged. Make sure the soil is moist consistently around the plant. Some varieties I have had grow in a large mound with some of the outer stems growing out across the ground. It won't hurt to cut the poor looking stems back to within a couple inches of the ground.

You know, I'm not positive but I don't believe the leaves are wilting, I will have to double check. I'm trying to be very careful about watering them.

I forgot to let you know, the leaves were not wilting, there's one branch up and the rest are low, I'll have to take a picture.
