Small Greenhouse Flower Garden: Best Annuals & Perennials for Color All Year

Flowers brighten any space. Start small with a well-defined goal for your greenhouse garden.

Extend Your Season with Annuals

Beyond impatiens, geraniums, marigolds, salvia—today's choices are captivating.

Cold-Hardy Picks

• Half-hardy perennials (survive light frost): Impatiens, heliotrope, tuberous begonias—riot of color
• Freeze-tolerant: Pansies, ornamental cabbage withstand extreme cold

Perennial Versatility

Long-lasting texture, color, form. Range from midsummer stars (Mexican sunflowers, zinnias) to neutrals (pastel stocks, lavatera).

Design Creatively

• Mix heights: tall/climbing + short/bushy
• Blend fragrance (stock, mignonette, nicotiana) with striking foliage (caladium, dusty miller, coleus)

Your small greenhouse becomes the ultimate relaxation abode.
