Add to My Garden Chinese rhubarb
Rheum officinale
The chinese rhubarb (Rheum officinale) are a group of large-leafed flowering plants in the buckwheat (sometimes called knotweed) family. This genus is most famous for its edible species. Although their leaves are toxic, their thick red stems are edible and sport a tart flavor – they're often used in desserts and pastries such as pies. Additionally, a handful of chinese rhubarb species are grown ornamentally, being prized for their large, showy leaves.

Just like people, each plant has its own preferences and needs. Devote time to understanding your plants so you can nurture them properly. Observe your plants attentively, learning from their growth patterns, and becoming more in tune with their needs as you grow together. Keep a watchful eye on new plants and seedlings, as they are sensitive to both overwatering and underwatering. Shower them with gentle love and attention, fostering their growth and strength. Let the rhythm of your local climate guide your watering habits, adapting your schedule to the changing weather and the needs of your plants. Amount and Approach

2. Let it rest for 10 minutes.
