Zinnia grandiflora, commonly known as Rocky Mountain Zinnia or Prairie Zinnia, is a perennial plant native to the southwestern United States and northern Mexico. It is part of the Asteraceae family and is known for its bright yellow flowers that bloom from late spring to early fall. This plant is well-adapted to dry, rocky soils and is often found in prairies and open woodlands.
Zinnia grandiflora thrives in full sun and requires minimal watering once established. It prefers moderate temperatures and can tolerate dry conditions. This plant does well in low humidity environments and is relatively easy to care for, making it suitable for outdoor gardens.
土壤
Zinnia grandiflora prefers well-draining loamy soil. It can tolerate poor soil conditions but performs best in soil that is not overly rich in nutrients. Good drainage is essential to prevent root rot.
肥料
A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied sparingly during the growing season. Over-fertilizing should be avoided as it can lead to excessive foliage growth at the expense of flowers.
换盆
While Zinnia grandiflora is typically grown outdoors, it can be repotted if necessary. Repotting should be done in the early spring before the growing season begins. Use a well-draining soil mix and ensure the new pot has adequate drainage holes.
传播
Zinnia grandiflora can be propagated by seeds or cuttings. Seeds should be sown in the spring after the last frost. Cuttings can be taken in late spring or early summer and rooted in a well-draining soil mix.
修剪
Pruning is beneficial for Zinnia grandiflora to encourage bushier growth and more prolific flowering. Deadheading spent flowers will also promote continuous blooming. Prune in the early spring to shape the plant and remove any dead or damaged stems.
毒性
Zinnia grandiflora is not toxic to pets or humans. It is considered safe for gardens where pets and children are present.
额外的
Zinnia grandiflora is drought-tolerant and can thrive in xeriscape gardens. It attracts pollinators such as bees and butterflies, making it a great addition to a pollinator-friendly garden.
