Zinnia 'Peppermint Stick' Seeds

Sow indoors in April or May, or direct outdoors from late May into June once the soil is warm. Zinnias dislike cold and root disturbance, so modules or small pots planted out whole give the best start.

Yes, they are one of the best. Cut when the stem just below the flower feels firm, and the blooms last well over a week in a vase. Picking regularly encourages the plant to keep flowering until the frosts.

Most flowers are streaked or speckled, but the pattern varies from plant to plant and some blooms come out lightly marked. That variation in a single bunch is a large part of its charm.

We always aim to make sure our customers love our products, but if you do need to return an order within 14 days of purchase (not including plants*), or any items are damaged, we’re happy to help. Just email us directly at hello@growtropicals.com, and we’ll take you through the process. 

Please note: we cannot be held liable for any packaging costs should the original packaging be discarded.

*Unfortunately we cannot accept returns of undamaged plants as these are perishable items and are not saleable upon return. If a plant is damaged, we will compensate for this as per our live arrival guarantee.

When placing your order, you can choose from three dispatch speeds to suit your needs: Economy (prepared and shipped within 4-5 days), Standard (3-5 days), or Express (dispatched the very next day). Please keep in mind that "dispatch" refers to the time it takes our team to prepare and pack your items before handing them over to the courier, not the total delivery time.

Shipping costs are based on your total order value and will be calculated at checkout, with free shipping automatically applied to all orders over £60. For a full breakdown of shipping prices see our Help Centre.

Additionally, to protect the health and quality of our live plants, orders containing plants are exclusively shipped Monday through Thursday. This careful scheduling prevents your plants from being stuck in a dark shipping depot over the weekend, ensuring they arrive at your door vibrant and healthy.
