"Spring is nature's way of saying, 'Let's party!'" observed comedian Robin Williams.One way to celebrate the outdoors this season is to peek inside the homes and gardens that open to the public for viewing.Here are five area home and garden tours happening in the next few weeks.AIA Fort Worth Homes TourArchitectural design junkies can experience four residential styles with the added bonus of speaking with representatives from each property's architects on the American Institute of Architects' second home tour.Architect Norman Ward's home, on acreage with trees and pasture, is made up of four pavilions under one roof, built in concert with its natural surroundings. Considerations were made for wind, sunlight and views.Architect Brandon Allen's 1948 brick home in Ryan Place represents the contemporary renovation of an older house, a completely reworked interior within the home's original footprint. Similarly, a 1925 craftsman bungalow remodel by Firm 817 has preserved the home's original character while updating the interior and adding on.The fourth home, a midcentury modern built in 1967 by noted architect Lee Roy Hahnfeld, remains largely unchanged. Its original architecture is complemented by the owners' collection of midcentury modern furniture and accessories."Our tour appeals to anyone interested in design, home renovation, anyone in the Metroplex thinking of hiring an architect. This is a demonstration of what local architects can do," says Alesha Niedziela, Associate AIA executive director.Details: Noon-6 p.m. Saturday and SundayTickets are $25, $10 for individual homes, available at the Center for Architecture, 3425 W. Seventh St., Fort Worth, and at each home on the tour.Tour home addresses are 240 Loma Blanca Lane, 3900 Bunting Ave., 3020 Sixth Ave. and 1740 Vinewood St., all in Fort Worth.For details, visit www.aiafortworth.org.Southlake Garden TourAlthough the Perennial Garden Society sponsors the Southlake Garden Tour, "we definitely don't discriminate," says tour co-chairwoman Beckie Underwood.The tour spotlights six Southlake gardens and features learning opportunities tied to characteristics of the gardens themselves. The educational component is what sets the Southlake tour apart, says Underwood. "We're providing some very beautiful gardens and the educational aspect of [gardening] at a very affordable price."The tour includes a certified natural habitat showcasing water conservation with drought-tolerant native plants, rain barrels and pond-supplied irrigation; a swimming pool that evolved into a pond when poor drainage and runoff were constantly wreaking havoc; a built-in mosquito-control misting system that resuscitated a shady back yard; and an English cottage-style garden thriving despite North Texas conditions.Experts on hand will include Tarrant County Master Gardeners; representatives from the city of Southlake, Alpine Materials and the Bob Jones Nature Center; and radio personality Marilyn Simmons, an expert on organic square-foot gardening.Details: 10 a.m.-4 p.m. SundayTickets are $8 in advance, available at Calloway's Nursery, 760 Grapevine Highway in Hurst, 291 E.

The tour, designed for gardeners and nongardeners alike, also hosts a plant sale of member-grown plants appropriate for North Texas and a raffle of garden-related items and services.Gardens include a 3/4-acre space of winding paths and vintage vignettes that backs up to a natural area; a former farm with flowers skirting unusual natural rock formations; and a spectacular outdoor kitchen with a fireplace and other areas of sanctuary for reflection and conversation."The fourth garden shows what can be done when you've downsized and you have a smaller garden footprint," says Susan Taylor, tour chairwoman. The front and side gardens of this zero-lot-line home display a water feature and an abundance of color and texture in every season, with more than 45 varieties of plant life."Our 'Water Smart' educational exhibits on rain harvesting and drip irrigation will appeal to everyone's desire for plants in bloom during our typically hot, dry summers," Taylor says.Tarrant County Master Gardeners and the club's members will be on hand to answer questions.Details: 11 a.m.-4 p.m. May 5Tickets $12 in advance, $15 day of tour.

And that area is known for it because of all the architecture. It's a beautiful area that needs to be celebrated," says Suzy Coleman, Historic Fort Worth special events coordinator.Ridglea Hills, once farmland, boasts properties with large lots, and the smallest garden on this tour is 1 acre. The largest is a gated community of townhomes on a 5-acre property that once hosted the sculpture garden of an oil baron. Today, townhome residents share a 1-acre pond graced by swans, a wisteria-draped gazebo and lovely landscapes of water lilies, junipers, azaleas, flowering quince and roses.A 3-acre property on the tour welcomes guests with 90 feet of Old Blush roses along the drive before delighting them with perennial and Japanese garden elements. Two other homes display gardens reflecting graceful outdoor living, with an alfresco shower, pools with cabana houses and a generous vegetable garden.The tour spotlights how, despite generous lots, "it's all been utilized for a family's use," says Coleman.Details: Noon-6 p.m. May 19Tickets $20 in advance, $25 on the day, and available at Archie's Gardenland, 6700 Camp Bowie Blvd., Fort Worth; Calloway's Nursery, 2651 S.
