Product Description:

Silybum marianum is a bold, upright annual or biennial with large, glossy green leaves marbled with distinctive white veins. The leaves are spiny along the edges, forming a dramatic rosette in the first year. In the second year, tall branching stems rise to display large, purple, thistle‑like flower heads surrounded by sharp, triangular bracts. Its imposing size, striking variegation, and architectural form make it a standout in wild gardens and naturalized plantings.

Growing Conditions:

Grow in full sun. Prefers well‑drained, moderately fertile soil and tolerates drought once established. Avoid overly rich soil, which can lead to excessive size. Allow seed heads to mature only if naturalizing is desired — otherwise remove spent blooms to prevent unwanted spread. Excellent for bold accents in wildflower meadows and tough, dry sites.

Ships in 3" pots. You will receive a plant similar to the ones pictured, though size and fullness may vary. Please understand that shipped plants have bumpy rides. A few broken leaves or small stems are normal during shipping and are not considered damage. Broken stems can be rooted once the cut end dries to start new growth. Plants may arrive semi‑dormant, and in winter they may naturally drop a few leaves. If your plant arrives rotting or dead, we will replace it. Please contact us with photo proof within 24 hours of delivery. After 24 hours, plant care becomes the buyer’s responsibility, though we’re always happy to answer questions and help you succeed. We also add brief instructions on getting started when you open your box. We want our plant babies to have happy new homes! 🥰

Heat packs are available to purchase in our shop for cold-sensitive plants. Keep in mind some plants we carry are very tropical and even cold, not freezing, temperatures can kill them. 📌IF YOU EXPECT COLD WEATHER, PLEASE PURCHASE A HEAT PACK! 📌 These are necessary for winter shipping, so I sell them at cost. I won't refund or replace any frozen plants unless you buy one!
