Rhododendron 'Catawbiense Grandiflorum' is an evergreen shrub of the species Rhododendron catawbiense, which belongs to the heather family (Ericaceae).
Produced at the Zymon Ornamental Shrubs Nursery, Catawba Rhododendrons are hybrids of the previously mentioned species. Botanically, the Catawba Rhododendron originates from North America and is characterized by good frost resistance and moderate growth rate.
In contrast to azaleas, also belonging to the heather family, rhododendrons do not lose their leaves in winter, and during extreme frosts, the leaves can curl into tubes.
When planning to cultivate rhododendrons in the garden, it is important to ensure several key conditions:

  • the rhododendron requires a semi-shaded and sheltered position, protected from the wind.
  • gleba przygotowana dla różanecznika powinna być kwaśna, próchniczna, przepuszczalnej i umiarkowanie wilgotna,
  • rhododendrons thrive best along the edges of small ponds, water features, or other bodies of water, where there is a moist microclimate.
  • rhododendrons definitely thrive better when planted in groups.

Rhododendrons dislike being transplanted, so it is important to properly prepare and choose a location for your desired plant. If you have any doubts regarding the selection or requirements of the plant, we invite you to contact us, and we will provide professional advice in choosing the plants.

Rhododendron 'Catawbiense Grandiflorum' is a spreading shrub with a wide habit. It blooms profusely from late May to June. The flowers are light purple with a red-yellow marking on delicately fringed petals, gathered in conical terminal inflorescences.
